Well I have releagted my SBT to the bedroom with a pair of active speakers!

Currently using my MacBook Pro streaming ALAC files via optical straight into my Rega DAC with excellent results and improvement over the SBT.

I want to buy a Synology DS212j NAS with 2 x 1TB WD Red harddrives, Is there any Mac experts out there who can advise me of getting my Macs iTunes library onto the NAS and for my Mac to always point to the library on the NAS

I want to hardwire the NAS to my DAC via USB, but be able to control iTunes library on the NAS with my iOS app

If you want to use iTunes to play music, the signal will have to come from your Macs optical or usb. The library can be on the nas, but you can't use iTunes to play it but have the music go straight from the nas to your dac. The best way to do that would be to use the Synology app Audio Station (a bit more info), which you install directly on your nas. You still use your Android/iOS device to control it with a free remote app, but it completely leaves your MBP out of the equation. You can then go straight from nas to dac. I don't use one, but I'm guessing your SBT can also access the music direct from the nas also. I used to use the iTunes remote app to play from a Mac mini, I find Audio Station and the DS Audio remote app just as good.

To get your music onto the nas, just create a folder called Music (or whatever) on the nas and copy the music from your iTunes library to it. New CDs are ripped with my MBP in iTunes, then I just copy it across the wifi network to the Music folder on my nas - Audio Station automatically adds them to its library and that's it, it's ready to play. There is also a Synology forum dedicated to Audio Station.

I've used a Mac direct to dac, Airplay to Atv into dac, and now nas into dac. I'm very happy with the nas into dac way of playing music. You can also use the nas as a Time Machine backup for your Mac.

Thanks Craig - I thought as much! Just that I seem to like the iOS Remote app, but heard the Synology app is as good!

thanks for the info!

SBT now in berdroom with Active speakers - SBT points to iTunes library on my MBP - Getting sorted now......got a Vinyl front end system in the Lounge along with my CDs in ALAC on my MBP which can be streamed upstairs to the SBT!

i've wrote this somewhere else, but why not keep things simple. I've a Synology 213 2x3 TB HD, and recently i've connected the NAS directly to Rega DAC with amaizing results !!! The iOS app work like a charm in my iPad commanding the DS Audio player, and faster that SBT app and SBT it self.

My library is mainly FLAC file, so i've never used itunes as a player.

I've connected my SBT to my NAD 3020i in my bedroom as well in last month preventing falls by the wayside...

You could always try a Sonos Connect to bypass the MBP. Personally, I prefer the UI of the Sonos software to the DS Music software and have the music library set up so it takes the music from my Nas. I use iTunes to rip my CDs and they go straight into the Nas folder I set up.

You can change the folder that music is saved to under Preferences, then under Advanced.
